Boston Celtics take Game Seven against the Washington Wizards 115-105

Boston trailed 76-72 late in the third quarter before ending the period on a 13-3 run, which was expanded to 22-5 in the opening minutes of the fourth as the Celtics' lead became 94-81. They won all four games at home in the series against Washington.

The Boston Celtics have advanced on to the Eastern Conference Finals after defeating the Washington Wizards 115-105 in Game Seven.

BOSTON (AP) - Ever since the Boston Celtics broke up their Big Three in 2013, they've sat idly this time of year while LeBron James, Stephen Curry and Kawhi Leonard have battled for National Basketball Association championships. Washington did fight back a bit making a 7-0 run of their own.

Monday's victor earns an Eastern Conference finals matchup with the defending champion Cleveland Cavaliers, who have been awaiting an opponent since sweeping Toronto on May 7.

"It's great. You always talk about it". Olynyk broke out everything in his arsenal, including his seldom used low-post game to slip some nifty finger rolls by smaller defenders.

"It was unbelievable", Olynyk said of coming through for the C's during Game 7, "especially to do it in front of our fans and the city of Boston".

San Antonio star forward Kawhi Leonard will miss Tuesday night's Game 2 of the Western Conference finals at the Golden State Warriors, leaving Spurs coach Gregg Popovich irate over what he felt was an avoidable injury.

The Celtics had to advance to the Eastern Conference finals against the Cavaliers to truly call this season a success.

Thomas finished the night with a team-high 29 points, but that's he status quo for him. In his senior year, he was able to rehabilitate his shoulder and complete an outstanding high school career, averaging 35 points a game, scoring a career high 54 points in one game.

It was a total team effort sparked by a spirited performance from Boston's Big Bench Three of Kelly Olynyk (26 points, five rebounds), Marcus Smart (13 points, six rebounds, four assists) and Jaylen Brown (nine points). The Celtics and Wizards were tied twice.

John Wall struggled to end the game, but it doesn't take away from the incredible season and postseason Wall had.

PRESSURE IS ON: Thomas and Wall.

Bradley Beal led the Wizards, playing their first Game 7 since 1979, with 38 points - including 24 in the second half.

Bradley Beal hit the first shot of the third quarter to give the Wizards their biggest lead at 57-53.

Something will have to give in Game 7. Much the same is true for Wall, who said he would think of this season as a disappointment if they forced Game 7 only to come up short.

Wall was ineffective down the stretch, unable to take advantage of the speed that coaches around the league maintain is unparalleled.

Even if the Cavs come out slow or rusty in Game 1, they should still be the favorites. On the moneyline, the Celtics are -220 favorites, while the Washington Wizards are +190 underdogs.
